Beat by the heat or beating the heat?

From AFP, "Heat forces pope to cut short address":

ROME (AFP) - Stifling heat has forced Pope Benedict XVI to cut short his address during his weekly general audience in Saint Peter's Square.

The pope, protected from the sun by a parasol held by an attendant, told 25,000 faithful, many of whom were bare-headed, that "as it is too hot, I will be briefer."

Benedict XVI also took less time in his traditional greetings to those present on Wednesday, ranging from senior prelates to newly-weds.

Temperatures went over 35 degrees Celsius (95 Fahrenheit) in Rome Tuesday, bringing summer to the Italian capital following a relatively cool spring.

Now here's my question: did Pope Benedict cut short his outdoor address because he was too hot or did he rather shorten it because he recognized that it was a hot day and many people in the audience were not well-equipped to handle it (so he cut it short more on account of their safety than his own)?
